I meant to reply to your thread quite awhile ago, sorry for the delay.
My favorite fishing road trip includes a handful of lakes all located in the Okanogan area of N. Eastern WA. The place that I make my base camp is;

It is located right along Spectacle lake. 50' from waters edge. They have row boats, as well as I think electric motors. A dock right outside your door. The rates are quite cheap, especially this time of year. Not to mention a whole lot of simple pleasure amenities. BBQ grill outside your door, horse shoes, swimming pool, store with the basics, etc. etc. You can sit on your back porch, have a wood fire outdoors, and be 50' from the water.
The fishing in Spectacle lake itself is fair for simple rainbows. I would go out in the moonlight and slow drag a fly around the lake, it was non stop action.
More importantly is there are so many other lakes in the area.
Another great road trip, with COMPLETELY different fishing is Omak Lake. This lake holds a rare species of trout, Lahontan Cutthroat trout. These are large fish, more like a small salmon. The lake is on an Indian reservation and requires a separate pass which is easily obtained in town. The fishing is OFF DA HOOK!! These are not 12" stocker rainbows, but fish are easily 3-4 lbs and can be upwards to 8-9 lbs. I think the state record comes from here, and is quite a bit larger still.
All that being said... It is the dead of winter, so would need to check your regs. on various lakes, etc. for what is open right now.
I have fished Omak in the 1st week of January, so you are probably safe to some degree there.
If you have any further questions, send me a PM.
